Title: Mobile knife folding mechanism for rotary printing machine - has swivel axis perpendicular  to knife movement and sheet supply direction
Inventor: BOETTCHER ANDREAS
IPC: B65H45/18
Filed: 1991-05-02
Abstract: The folding mechanism comprising a folding knife (3), two folding rollers (4), a supply member (5) and discharge device (6) is fixedly connected to a drum (7) in the machine frame (1) and can be fixed in two oppositely turned positions so that the folding board acts from bottom to top or top to bottom. The supply member extends over the entire width of the folding mechanism so that the sheets can also be passed through without being folded. The reversible supply device can supply sheets selectively from two opposite directions. USE/ADVANTAGE - When swivelling the folding mechanism around 180 deg. to product another type of fold it is not necessaryu to adjust the supply and discharge devices.

Title: Coupling between tool-holder and machine tool
IPC: B23B29/04
Filed: 1991-05-31
Abstract: The mechanism consists of a cylindical toolholder coupling piece (5) with a coaxial pin (23) which locate in the coupling body (3) and an integral draw bolt (37) respectively. Clamping is facilitated by bevel gear arrangement (35, 41) which causes the draw bolt (37) to be pulled, by means of a thread arrangement (40), so as to cause the cam mechanism (69) to act upon the angled faces (19, 71).     The clamping device (51) may have an eccentric cam offset from its axis (43) which locates in a recess in the drawbolt (37) and by rotating the clamping mechanism about its axis causes the drawbolt to be moved along the major axis (11).

Title: Solar collector panel - contg. self-circulating two-component heat carrier liq., giving reduced heat loss at the cover plate
Inventor: BECKER FRIEDRICH
IPC: F24S10/80
Filed: 1991-08-17
Abstract: In a solar collector which is covered by a radiation transparent pane (2) and is mounted in a heat insulating support (1), (i) the collector employs a two-component heat carrier liq. at least one component of which evaporates at the operating temp.; (ii) the liq. trickles through heat insulating elements (7), e.g. square or hexagonal honeycombs, and takes up heat by constant evapn. of the component(s); (iii) the evaporated component(s) and the residual liq. pass along a light absorbing surface (8) to the lower end of the sloping collector, at which point useful heat can be extracted; (iv) the liq. then passes through pipes or vessels (9) behind the light absorbing surface (8) for residual heat transfer to liq. flowing in front of this surface (8), the expansion of the evaporated compound(s) being used to advance the vapour and the liq. and the pipes or heat exchange vessels (9) being so thin that adhesion forces prevent liq. backflow; (v) the liq. then passes into a gap (3) between the cover plane (2) and a light transparent pane (4), opt. sepd. by an air gap from a further underlying light transparent pane (5), liq. permeable connections (6) of capillary structure being formed through the light transparent pane(s) (4,5) for trickle passage of the liq. onto the collector inside where the liq. can evaporate again. ADVANTAGE - The flat solar collector employs a two-component heat carrier liq. which circulates automatically and provides additional heat take-up by evapn. and condensation. The design reduces heat loss at the cover plate.

Title: Stable multiple layer metallisation contacts for cpd. semiconductors -  consist of contact metal, barrier of titanium-tungsten-nitride and wire-bond metal and can be easily processed
Inventor: NIRSCHL ERNST DR
IPC: H01L23/485
Filed: 1991-09-06
Abstract: The metallisation contacts for making wire-bonds to the semiconductor device consists of metal 1, metal 2 and a barrier between them of Ti-W-nitride (TiWN). The top layer is pref. Al, an Al-alloy or Au. The last two layers, resp. all three layers, are pref. deposited in a single process step. An adhesion promoter can be deposited between the barrier and the second metal layer. USE/ADVANTAGE - The TiWN layer, which acts as a diffusion barrier, can be easily made thick enough to compensate for roughness of the first metal layer. The layer does not change its compsn. during subsequent heat-treatments at temps. up to 550 deg.C for 1 hour. The barrier  can be easily etched in a wet etching step. It can be deposited in a vacuum depsn. apparatus in sequence with the other layers, avoiding the substrate being exposed to the ambient and so avoiding contamination depsn. and reaction in ambient air. The resistance of the layer can be adjusted by the N-content. The metallisation system is used in the mfr. of III-V semiconductor devices, especially opto-electronic devices and allows reliable operation even at temps. above 100 deg.C.
Patent DE-4130073-A1 (DE)
Inventor: DALFERTH HANS DIPL ING
IPC: F16H55/30
Filed: 1991-09-06
Abstract: In the case of a deflection chain wheel of the pocket type, in particular one for chain blocks of hoisting equipment of small overall height, both the vertical links (7) and the horizontal links (4) are supported by supporting surfaces (5, 8). The supporting surfaces (8) for the vertical elements (7), in particular, have a comparatively low surface hardness of about 680 VH, thereby ensuring that, when the deflection wheel is put into operation, the vertical chain links very quickly create a bed which ensures uniform distribution of the forces acting between the deflection wheel and the chain links to the vertical and horizontal chain links and, in particular, protects the horizontal chain links (4) from bending fatigue fractures. <IMAGE>

Patent DE-4137857-A1 (DE)
Inventor: STRECKER ERNST PETER PROF DR M
IPC: A61F2/00
Filed: 1991-11-16
Abstract: The device comprises a prosthesis (15) in the form of a hollow body which is compressed against the action of return elastic forces on a reduced cross-section in comparison with a broadened useful position and held in this position by means of a removable casing (14).

Title: Device using centrifugal force for subjective simulation of forces - is used to influence movement of body
IPC: B64G7/00
Filed: 1991-11-21
Abstract: Between two horizontal double bearers (6) which at their ends are located on driven rollers or wheels (8), a cardanically suspended cabin, cockpit or passenger cell is so mounted that it can move freely along the bearers. It moves from top to bottom along the ordinates, and the imbalance occurring is compensated by counterweights (7) which are counterposed to the cabin. The complete system is therefore located only on the rollers or wheels so that a circular movement of the complete support frame is only possible. USE - As a simulating training unit for large and small aircraft, including very rapid fighter aircraft, for all types of surface vehicles, including formula 1, bobsleigh sportsmen, etc..
